如何使用mypyc编译pydantic BaseModel？

Question

在我们已经安装的环境中：

pip install -U pydantic mypy

举个例子

test_basemodel.py

：

from pydantic import BaseModel


class A(BaseModel):
    pass

我们运行命令：

 mypyc test_basemodel.py

并看到：

根据https://mypyc.readthedocs.io/en/latest/native_classes.html#inheritance

大多数非原生类不能用作基类

是否可以使用 mypyc 编译 pydantic BaseModel？ Pydantic 与 mypy（不是 mypyc）配合得很好，并且 mypy 与 mypyc 的联系如此紧密，以至于我不敢相信这种关系没有明确记录，更不用说不受支持了。

感谢@dROOOze。

答案是从

import BaseModel

到

pydantic.main

，而不是 pydantic。我仍然不明白为什么没有明确记录这一点

from pydantic.main import BaseModel


class A(BaseModel):
    pass
